Vibratory plate retouching apparatus

INVENTOR EVERQRD L.JOHN5ON ATTO RN United States Patent This inventionrelates to vibrator apparatus for use in retouching photographic filmsor plates. More partic ularly, the invention deals with an apparatus orthis type and kind wherein the plate used for supporting the film orpicture to be retouched is vibrated or agitated in applying retouchingmarkings to the film or picture. Still more particularly, the inventiondeals with an apparatus ofthe type and kind which is collapsible tofacilitate shipmentand storage thereof.

The novel features of the invention will be best understood from thefollowing description, when taken together with the accompanyingdrawing, in which certain embodiments of the invention are disclosedand, in which the separate parts are designated by suitable referencecharacters in each of the views and, in which:

Fig. l is a perspective view diagrammatically illustrating theretouching apparatusin set-up condition with part of the constructionbroken away.

Fig. 2 is a partial section on the line 2-2 of Fig. 1 on an enlargedscale.

Fig. 3 is a partial section on the line 3-3 of Fig. 1 on an enlargedscale and omitting part of the construction; and

Fig. 4 is a partial section on the line 4-4 of Fig. 1.

In Fig. 1 of the drawing, I have shown diagrammatically my improvedretouching apparatus in set-up condition. The apparatus comprises arectangular base frame to which is hinged, as seen at 11, a platesupporting frame 12, also rectangular in form, the frame 12 beingnormally collapsible on the frame 10 and held in raised operativeposition by a pair of easel rods one of which is shown at 13 in Fig. 1,the rods being pivoted to the upper portion of the frame and collapsibleWithin the frame 10. The frame 10 preferably has cushion supporting feet10 for preventing marring of the surface on which the apparatus issupported.

The frame 12 includes a back wall or panel 14 having a round opening 15centrally of the upper portion thereof, and adjustably supportedrearwardly of the opening 15 is an electric bulb 16 having a flexiblearm support, part of which is seen at 17 in Fig. 1. Yieldably supportedon the Wall or panel 14 is a vibratory plate or picture mount 18composed of suitable translucent material. The plate 18 is supported onthree sponge rubber pads 19 and is aligned on the wall 14 by three bolts20 on the shanks of which are disposed sponge rubber bushings 21 whichfit in apertures 22 in the plate 18, this construction being clearlyshown in Fig. 3. It will also be noted in said Fig. 3 that the nut 23 ofthe bolt bears against a rubber washer 24.

To further support and hold the plate 18 on the wall 14, I provide twoU-shaped sponge rubber blocks 25 secured to the wall 14 by bolts 26 inthe manner clearly illustrated in Fig. 2 of the drawing. Side edgeportions of the plate 18 fit in the channel or slot 25 of the blocks asnoted in Fig. 2. From the foregoing, it will be apparent that the plate18 has an all-rubber mounting on 2,740,345 Patented Apr. 3, 1956 thewall 14 so as to facilitate vibratory action of the plate by thevibratory means which is employed.

At 27, I have shown an electric vibrator having the vibratory post 28with which is coupled one end portion 29 of a transmitting coil spring30. The other end 31 of this spring is coupled wjth a post 32 attachedto a strip 33 secured to the plate 18 by screws or other fastenings asat 34.

Supported on the frame 12 are two negative supporting spring arms 35 and36 having cushioned tips 35, 36' which will engage a negative andprevent marring thereof. At 37, I have indicated in dot and dash linesthe outline of a negative for a suitable picture representation as at37' disposed in alignment with the aperture 12 and which is to beretouched. Also supported on the frame 12 is a hand supporting platform38 which extends over the wall 14 and is in spaced relation thereto andprotrudes in an upward direction so that the hand can be supported inclose proximity to the picture representation as at 37'.

In the operation of the device, a suitable retouching tool or implementis supported in the end which rests on the platform 38 with the point ormarking end of the instrument arranged over the area of the picture 37'to be retouched. Then the vibrator is put in operation to vibrate theplate 18. Vibratory action of the plate 18 will provide the necessarydistribution of the mark and the marking implement will simply be movedto change the areas to be retouched.

It will be understood that the plate 18 is formed of any suitabletransparent or translucent material, glass and plastics being desirable.It is also preferred that the translucency be substantially similar towhat is generally referred to as frosted glass.

The electric vibratory device 27 diagrammatically shown in Fig. 1 is ofthe type and kind disclosed in my prior Patent No. 2, 404,134, grantedJuly 16, 1946, the post 28 being similar to the vibratory post asdisclosed in said patent.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. A vibratory photograph retouching frame, comprising a pair ofrectangular frames hingedly coupled for relative movement, meanssupporting one frame in angular position with repsect to the otherframe, a panel in one of said frames, said panel having an opening inthe central portion thereof, a translucent picture supporting plate,means comprising sponge rubber supports mounted in connection with saidpanel and engaging the plate to yieldably support and position the plateon said panel, means for yieldably supporting a picture on said plate inalignment with the opening in said panel, means rearwardly of the panelopening for illuminating that part of the plate exposed to said opening,an electric vibratory device, means yieldably coupling said device withsaid plate to vibrate the plate on said panel, said paneled frame havinga hand rest platform fixed to one side of the frame and extending overand in spaced relation to the panel of said frame, and said second namedmeans comprising bolts having yieldable bushings arranged in aperturesof said plate in yieldably positioning the plate on said panel.

2. A vibratory photograph retouching frame, comprising a pair ofrectangular frames hingedly coupled for relative movement, meanssupporting one frame in angular position with respect to the otherframe, a panel in one of said frames, said panel having an opening inthe central portion thereof, a translucent picture supporting plate,means comprising sponge rubber supports mounted in connection with saidpanel and engaging the plate to yieldably support the plate on saidpanel, means for yieldably supporting a picture on said plate inalignment with the opening in said panel, means rearwardly of the panelopening for illuminating that paItof the plate exposed to said opening,an electric vibratory device, means yieldably coupling said device withsaid plate to vibrate the plate on said panel, said paneled frame havinga hand rest platform fixed to one side of the frame and extending overand in spaced relation to the panel of said frame, said second namedmeans comprising bolts having yieldable bushings arranged in aperturesof said plate in yieldably positioning the plate on said panel, andU-shaped yieldable ciips enveloping peripheral edges of said plate andfixed to said panel.
